Remove Data from old installation

[PMTGaming]

Is there a way to remove all data from Jellyfin so I can reinstall it?

During reinstallation, I get stuck at selectserver.html, and there is no connection to the available server.

hi,
maybe just clean the cache of your browser will allow you to comnect ?

Hello,
Thanks for your response.
The initial setup was completed by clearing the browser cache.
However, Jellyfin only works until I restart the server. After that, the same error as before occurs, and the only solution is to reinstall, clear the browser cache, and repeat the process.

So i just found out that when i restart jellyfin, from the qnap app center it keeps working, only the restart button inside jellyfin seems to be corrupted.
But this works for me as is now.
